Stäubli Fluid Connectors supplier in Romania
Hydraulic and pneumatic quick couplings for industry
Headquarters: Switzerland
Who is Stäubli Fluid Connectors and what does it make?
Stäubli Fluid Connectors is the Swiss maker of quick couplings and fluid connectors, with a range of hydraulic, pneumatic and special-gas couplings organised by working pressure and locking type. The RBE series covers modular coupling for all types of fluids and gases — hydrogen, argon, nitrogen, helium, steam, solvents and acids — with a maximum pressure of 450 bar and nominal diameters between 3 and 19 mm, and the RBE/TM version is intended for railway and nuclear applications. Stäubli offers access to a range of couplings for difficult media.
In the strictly hydraulic segment, the range includes the SPX and SBA couplings with ball locking for high pressure (450 bar), CBX for medium pressure (also with ball locking, up to 450 bar on smaller diameters), MPX for medium pressure without fluid loss (315 bar) and, at the upper end, HPX with threaded locking at 500 bar and THL for very high pressure, up to 1,000 bar, operated with a single button. The SPH/BA series is a more compact 350 bar version, originally developed for motorsport, where weight and coupling speed matter as much as sealing.
For the Romanian market, the Stäubli Fluid Connectors range makes sense in high-pressure hydraulic installations in process industry, on test benches and in applications where quick coupling and uncoupling without fluid loss is a safety requirement, not just a matter of comfort.
What do we supply from the Stäubli Fluid Connectors range?
| Product | Description |
|---|---|
| RBE Modular Quick Couplings | Modular couplings for all types of fluids and gases — hydrogen, argon, nitrogen, helium, steam, solvents, acids — with a maximum pressure of 450 bar and nominal diameters from 3 to 19 mm. Stainless steel construction, with a push-button locking system and a coloured identification disc to prevent wrong coupling. |
| RBE/TM Couplings for Nuclear Handling | A version of the RBE range, for railway and nuclear applications. |
| SPX / SBA High-Pressure Hydraulic Couplings | Hydraulic couplings with ball locking, for working pressures of up to 450 bar, with nominal diameters of 6–16 mm (SPX) and 8–15 mm (SBA). Designed for high-pressure hydraulic circuits on mobile machinery and process installations. |
| HPX / THL Very High-Pressure Hydraulic Couplings | HPX uses threaded locking for 500 bar on diameters of 8–33 mm, and THL covers the very high-pressure segment, up to 1,000 bar, operated with a single button, for couplings on small diameters where the working pressure is extreme. |
Why Stäubli Fluid Connectors?
- Range in clear pressure steps, from 315 bar (MPX) up to 1,000 bar (THL), so you can choose exactly what is needed
- The RBE series covers special gases (hydrogen, argon, nitrogen, helium) in addition to classic hydraulic fluids
- RBE/TM version for railway and nuclear applications
- SPH/BA couplings developed for motorsport, with quick coupling and low weight
- Ball or threaded locking, depending on the series chosen, for the right balance between speed and vibration resistance

- Motorsport — compact SPH/BA couplings, quick coupling
How do we supply Stäubli Fluid Connectors in Romania?
We bring in Stäubli Fluid Connectors couplings to order through supply channels in the European Union; our confirmations depend on the exact series requested — for very high pressures (THL) or the nuclear RBE/TM versions, we obtain the availability confirmation ourselves when ordering. To order, usually 1–4 weeks. For a quotation, the customer needs to send us the series wanted (RBE, SPX, CBX, HPX, THL etc.), the working pressure of the circuit and the nominal diameter required.
Delivery times for the RBE/TM versions are given in the quotation, following a specific request.
Frequently asked questions about Stäubli Fluid Connectors
What products does Stäubli Fluid Connectors make?
Stäubli Fluid Connectors makes quick couplings for fluids, gases and high-pressure hydraulics, with ranges organised in pressure steps from 315 to 1,000 bar. The RBE series covers special gases such as hydrogen and argon, while versions such as SPX, CBX and HPX are dedicated strictly to industrial hydraulics.
How do I choose a Stäubli coupling by code?
The code indicates the family and the pressure step — RBE for gases and various fluids, SPX/SBA/CBX for medium-to-high-pressure hydraulics, HPX and THL for very high pressures. Send the working pressure and the nominal diameter required to identify the correct version.
How do I choose a Stäubli quick coupling?
Stäubli covers industrial quick couplings; the exact model depends on the working pressure, the nominal diameter and the locking type — send the circuit parameters for a specific recommendation.
Do you supply Stäubli Fluid Connectors couplings in Romania, and how long does it take?
Yes, we bring them in to order through supply channels in the European Union, usually in 1–4 weeks, depending on the series requested and any additional certification requirements.
What do I need to send for a Stäubli quotation?
Send the series wanted if you know it, or the working pressure of the circuit, the nominal diameter and the type of fluid handled, so that we can identify the right coupling from the RBE, hydraulic or very high-pressure range.
How do I request a Stäubli Fluid Connectors quotation?
Send the Stäubli Fluid Connectors code from the nameplate and the quantity; we reply in English with availability and the lead time written in the quotation.
